Solution :-

Let us assume that,

  • Initial price of milk = Rs.10x
  • Initial consumption = 10y litre .

we know that,

  • Price * consumption = Expenditure .

So,

→ Initial Expenditure = 10x * 10y = Rs.100xy.

now,

→ New price of milk = 120% of initial price = (120 * 10x)/100 = Rs.12x.

and,

→ New consumption = 85% of initial consumption = (80 * 10y)/100 = 8.5y litre .

then,

→ New Expenditure = New Price * New consumption = 12x * 8.5y = Rs.102xy

therefore,

→ Total Loss = New Expenditure - Initial Expenditure = 102xy - 100xy = Rs.2xy.

hence,

→ Loss % = (2 * 100) / 100xy = 2% (Option 2) (Ans.)
